I may not list all of them, Strengths: the Continential army was fighting to protect something (which can help with morale) and fighting on their homeland. The British Army was greater in numbers, better trained, and had more money to back them up. Weaknesses: The Continental army was poorly trained, had few funds, and was not well supported by their government. The British army was tired, harder to feed (because of the size), and it took longer to get them resources (their homeland was across the ocean).
